The electron impact and chemical ionisation mass spectra of twelve pertrimethylsilyl derivatives of desulfoglucosinolates deriving from naturally occurring parent compounds are described and discussed. Series of characteristic ions, mostly comprising molecular ions, render mass spectrometry of such derivatives, in combination with gaschromatographic separation, a useful tool in the identification of
描述和讨论了十二种源自天然母体化合物的磺基硫代葡萄糖苷的全三甲基甲硅烷基衍生物的电子冲击和化学电离质谱图。系列特征离子(主要包含分子离子)使此类衍生物的质谱与气相色谱分离相结合,是鉴定已知和新型芥子油苷的有用工具。尽管存在局限性,但是该方法的范围很广。因此,具有甲基亚磺酰基取代的侧链的大量天然存在的芥子油苷在其过三甲基甲硅烷基化的脱硫芥子油苷衍生物的尝试气相色谱中经历分解。
